When dumping FDEs, `readelf` prints new location values after `DW_CFA_advance_loc(*)` instructions, which looks quite convenient: ``` > readelf -wf test.o ... ... FDE ... pc=0000000000000030..0000000000000064 DW_CFA_advance_loc: 4 to 0000000000000034 ... DW_CFA_advance_loc: 4 to 0000000000000038 ... ``` This patch makes `llvm-dwarfdump` and `llvm-readobj` do the same.
